ESAS 2018 - Poster Programm

Importance of the Conference Poster Session in Analytical Chemistry

Analytical chemistry underpins critical applications across environmental monitoring, materials science, pharmaceuticals, food safety, and forensic investigations. Poster presentations at major symposia offer rapid insights into emerging methods, instrumentation advances, and novel sample treatment strategies. Bringing together diverse techniques highlights cross‐disciplinary innovation and accelerates adoption of best practices in laboratories worldwide.

Objectives and Overview of the Poster Program

The poster session comprised 74 contributions spanning cutting‐edge atomic spectroscopy, mass spectrometry, X-ray spectrometry, and laser‐based analysis. Key objectives included:

• Identification and characterization of nanomaterials by high‐resolution graphite furnace AAS and LIBS
• Investigation of trace metal mobility and speciation in soils, biological tissues, and historic artifacts
• Development of hyphenated techniques for element and species quantification at ultra‐trace levels
• Implementation of novel data evaluation workflows using chemometrics and programming tools
• Advancements in reference material synthesis and method validation for quality assurance

Methodology and Instrumentation

This extensive program highlighted use of the following instrumental platforms:

• High‐resolution continuum source graphite furnace atomic absorption spectrometry for coated nanoparticles and trace sulfur
• Laser‐induced breakdown spectroscopy (LIBS) and dual‐pulse LIBS for soils, concrete, asphalt, wine, and zeolites
• Laser ablation inductively coupled plasma‐mass spectrometry (LA-ICP-MS) for imaging of biological tissues, forensic fingerprint analysis, and battery materials
• Liquid chromatography and capillary electrophoresis coupled to ICP‐MS for selenium, chromium, arsenic, and manganese speciation
• Total reflection X-ray fluorescence (TXRF), micro-XRF and CE-XRF for metal mapping and speciation studies
• Glow discharge mass spectrometry for depth-resolved isotope dilution in battery components
• Plasma optical emission spectrometry (ICP-OES, ETV-ICP-OES) for lubricating oils, plants, and reference materials
• Asymmetrical flow field-flow fractionation and supercritical fluid extraction for nanoparticle characterization in consumer products
• Python and design-of-experiment approaches for data processing and method optimization

Main Findings and Discussion

Collectively, posters demonstrated significant improvements in sensitivity, spatial resolution, and sample throughput. Highlights included successful discrimination of silver nanoparticle coatings, detailed mapping of platinum distribution in biological tissues, and robust speciation protocols for toxic and essential elements in environmental and food matrices. Multivariate calibration and acoustic signal analysis enhanced quantitative accuracy in LIBS, while new reference materials and green extraction methods supported sustainability goals. Integration of programming tools streamlined large data set evaluation and ensured traceable, reproducible results.

Benefits and Practical Applications

These methodological advances offer practical benefits including:

• Rapid on-site screening of contaminants in soils, water, and building materials
• High‐throughput quality control in pharmaceutical and food industries
• Forensic identification of gunshot residues and adulterants in consumer products
• Non-destructive investigation of cultural heritage and archaeological artifacts
• Detailed element and isotope distribution studies in battery research and environmental health

Future Trends and Possibilities

Emerging directions identified by the posters include miniaturized and field-deployable analytical platforms, further coupling of separation techniques with high-resolution mass spectrometry, and integration of artificial intelligence for automated data interpretation. Continued development of green sample preparation, advanced reference materials, and real-time imaging methods promises to extend capabilities in ultra-trace analysis and spatially resolved investigations.

Conclusion

The breadth of research presented underscores a vibrant landscape in analytical chemistry, driven by novel instrumentation, innovative sample handling, and sophisticated data analysis. Adoption of these advances will strengthen laboratories’ ability to address complex challenges in environmental protection, public health, industrial quality control, and beyond.
